BeCu-Free Update: Comparison @360+ hours

This tool string is entirely BeCu-free (with the excpetion of the threaded ring on the end), has seen over 360 hours of down-hole time, and is ready to handle a lot more.

Here's a closer look at each component:

Next week, we put together the full string without BeCu, and send it downhole. Check back on Monday for the send-off.
